What philosophical arguments does Chapter 8 of the Sai Satcharitra make about the purpose of human life?

Chapter 8 of the Sai Satcharitra presents a profound philosophical argument about the purpose of human existence. It posits that the true duty of human birth is the attainment of the Supreme Self, or Paramatman. The text argues that if a person's life is spent only on basic activities like eating, sleeping, fear, and mating, it is no different from the life of an animal like a dog or a pig. As stated in this chapter, such a life focused merely on nourishing the body and sensory pleasures is considered useless. A true human is described as free, fearless, and independent, and the ultimate success of birth is the realization of the Eternal.
